TO ALL WHOM IT MAY CONCERN: v i:

Be it known that I, WILLIAM BALL, of Ohicopce, county of Hampden, andState of Massachusetts, have invented certain new and usefulImprovements in Machines for Stamping Ores or Mineral Rock, Ste.; and toenable others skilled in the art to make and use the same, .Iwill-proceed to describe, by referring to the drawings, in which thesame letters indicate like parts in each of the gures.

The nature of this invention will be understood from the specificationand drawings, in which- Figures 1, 2, 3, show the plan and constructionof thevfoundation, with a portion of the framework.

Figure 4 shows a view of a double and single beam, which connect theperpendicular posts, and through or in which the steam-pistonvrod andthe stamp-shaft are secured and work.

Figures 5 and 6 show a front and side view, 'in section', of themortar-box and mortar.

Figure 7 is an elevation of the stamp-shaft, partly in section. ,I

Figures 8, 9, and 10, are views of detached portions of said stamp-shaftand hammer-head.

vIn figs. 1, 2, 3,`A is a timber foundation, bedded in the ground, eachsuccessive tier-of which is placed crosswise, one tier upon the other,and a little distance apart, so that apertures will be producedin theirangles from top torbottom through the several tiers, through whichapertures, bolts B are allowed to pass, the lower end through thegirders C, and the upper ends throughthe lower iiange of the cast-ironsill D. By means of these bolts the-whole structure or foundation oftimbers is bound rmly together,-and, the interstices (when I bedded inthe ground) are filled with grout,`thus rendering the foundation solid.

This sill D is made of metal, .in order to produce a broader base andgreater solidity theret'fnvthan can .be conveniently obtained in onepiece of timber, for'the purpose of taking or aiording'a broadersurface-bearing upon and across the ends of the sills A, Ythebase-bearing surface of which (sillD) is about three feet wide.Ordinarily, good sound timber eannot'be obtained, which will square upover eighteen inches, which, of course, will'cover only eighteen inchesbearing-surface, and thesevere usage to which they are subjected willvery soon batter the timbers, much to their injury or entiredestruction. For `these reasons I have adopted iron sills D, thusproducing a broadbearing-surface in one piece -to-rest upon thesills A,and a firm, unyielding support for the stamp-frame sills and thespring-timbers E. The metal weight of these sillsD is about three touseach. These' sills D support the whole machine, with its framework, themetal .weight ofwhichA is about thirty-two tons each. v i i 4 F arecross-timbers, about seventeen by twenty inches square, each endfofwhichis secured to the outer ends of the metal sills D. ,Gr arecross-timbers, about sixteen by eighteen inches square, the endsof'whieh are secured rmly to the timbers F, about four feet equidistantfrom the centre thereof. In the centre of these timbers are securedperpendicular posts, H, about eighteen vinches square, which serve assupports for'the stamp and its mechanism. These timbers or posts H aresupported byibraces I. The foot ot' each brace is firmly secured to theouter ends o f thetimber F. The upper ends of these braces are firmlysecured to the posts H.

The spring-timbersiseven in'number, and about thirteen by eighteeninches square)E are s kived oit` on the upper side, from a point abouteighteen inches each way from the centre, down to a thieknessofaboutnine inches atl their ends. These'timbers are arranged side by sideybetween the sills F.v 'J is a metallic bed-plate,ofabcut ten tonsweight, which, for convenience of transportation,'may'be made in twoparts. Its shape will-henndera stood from the drawings. It isof suchsize as to nearlyiill the space between the timbers GF, and has itsbearing directly upon the spring-timbers E. The stamp-mortar (about tentons weight) has its foundation upon the centre of the bed-plate Thewhole depth of the foundation timbers lwill beabout twelve feet.

-Heretofore only three spring-timbers, E, havebeen used to support thecast-iron bed upon whichy the mor-V tar is secured, which timbers haveproved insuiicieut for the work that is .put-,upon them; consequently,infroui six to ninemonths they break, and cause great damage invariousfways. To avoid'this diiculty, Isubstitute a greater number oftimbers, and place the bed crosswise, instead of lengthwise, (asheretoforc,) which allows or" four additional timbers, thus producing abroader and steadier foundation to support the mortar andth'o frameworkof the machine', and at the same time producing a greaterspring'surt'ucev to sustain the blow of the hammer.

The metal sill D is provided (instead of the' timber sills)because theycan be made of any desirable siz'e.

width, or shape, so as -t-o secure a broader bearing-surface in onepiece upon the foundatiomtimb'ers A,'and also to more perfectly securesaid sills I) firmly upon the foundationitimbers A by means of-bolts B.l

In figs'. 5 and 6,1a is a stamp-mortar; a is a mortar-box, twsides'ofwhich are perpendicular and parallel with each other.- Flanges aare formed on each of these parallel sides of this mortar orbox,perpendicular, and near the centre thereof, for thepurpose of securingsaid mortar in a-n erect and firm position to the posts H, while themortar itself rests upon the bed-plate J'. This mortar-box, sides, top,and anges are all made in one piece oi `cast metal, several of.which-are new in use. The inner sides and the vunder side of thetop arolined with about halfsinch metal plate.` The top plate of the box'isprovided with apertures to receive the hoppers a, through which thematerial is introduced into the machine, and has also a centralaperture, in

'which is4 secured a dange bell-.shape necking, cl, through which theshaft with its stamp-head may be introduced, before putting thepacking-ringin place and while setting up the'maehine. The hoppers aiarc ,made of metal, and lined with metal, so that the' parts most liableto wear away maybe easily and quickly re-linod, when neces. sary. Theshape and proportion -of these hoppers will be understood frein thedrawings# The aperturethrough whichthe shaft works is. providcdwith aiianged'bell-shape necking, d, made in two i parts, and secured togetherVby flanges, and having a tubular-ring rim, c, and funnels e. Saidtubular rim, e, is

Yprovided with perforati'ons or jets, at regular intervals, on.4 theinside, und near the bottom thereof. The'object of these, the funnelsc'and jets, is to introduce a supply of'watcr into said tubular rim,'.andthence, through the orifices,A in a direction downward and towards thestamp-shaft, the object of whichisto keep down thespla'sh and supply thestamp with water. l Y i f d are water-packing rings, tted upon theinside flange of the necking el, andsecured to the top plate of the boxa. .Between these rings is secured a leather ring, d", which projectsiuwardgnearly to the stamp-shaft,

'o r so as to leave about anequal space around and between its edge andtheside of saidA shaft, so as to allow a body or equal sheet of water toflow all around said shaft-into the box, for the purpose ofcounteracting the splash or rising of material produced from the actionof the stamp-hammer. 4The opening'of this leather ring v'is of about thesame'size of the shaft at its-highest point of altitude; that is, theinsidediameter of the ring is nine'inches and the diameter ofthe shaftis eight inches, which allows half aniineli play around the shaft, but

the shaft,when elevated to its'highest point, is nineiinches n diameter.in the ring, and nearly or quite fillsthe` opening in the' leatherring, and consequently the flow of water.A for the moment ischcclred,`until the shaft again drops, causing the splash to'rise, when theaccumulated supply of water, with the regular dow thereof, lfallsthrough the space, between the leather ring and shaft and counteraetsthe rising splash or material.

In addition to this packing Ialso secure a clamp-iiange, L, to the shaftK, just above the neeking,'the4 object of which is toprevent orcounteract any splash or gritty water. that risesl upwardl between theleather ring and shaft; which will sometimes oecurwhentheleather ringbecomes worn.

I also provide a metal ring, h, made in two parts, havingan openingabout twelve inches in diameter, and

'having its edge curveddownward, more or less, which ring is securedaround the stamp-`shaft opening on the under side ofthe top plate ofthebox a', between said plate andthe lininlg,vthe cbject'of which is tobreak the greater portion of the splash from comingin contact with theleather ring and the stamp-shaft. The inside diameter of the mortar aismade largerv ator near theA bottom than it is at the top. The stavesc', ten in num.

ber, (more or 1053,) are made of corresponding shape,- so that, whenthey are all inserted to their place, closely side by side around thering pf. the hammer, block, or anvil e, and the last stave (made wedgingor dovc-tail shape) is inserted and drawn back to itsplaee or positionwith the others, against the wall of the ppt, by'means of a bolt, x, itwill bind `the others closely in their respective places. The mortar-dieor-bed`(the shape o? which willV be clearly seen in fig. 6) is slightlyconical shape, and nearly the same diameter of the inside diameter ofthe ring. 'The staves are. also made thicker at their lower ends than attheir upper ends, and the outside diameter of the stavcs, when placedcompaotly together in the pot, are larger at their base than at theirupper ends, the object ofwhich is to prevent them fromjumping upwardout'of place' from the jar or working ofthe stamphammer. l

l f are sieves or gratings, through or against which the water Vorchoice metal splashes and escapeii from the machine through' the spouty. These perforated plates are-secured in each side ofthe box-opening,(front and rear,) Aso as to be easily taken outandreplaced, and held byplates ,and screws at their upper ends.

` f is a metal framework, secured upon the outside of the mortar-box,(front and 1ear,) and having grooves -to receive the edges of the metalsplash-plate. It is-also provided with a trough and-spout at its lowerside,

which conducts the wash from 'the machine into a receptacle arrangedtherefor. IWithout: these plates the water with the mingling materialwould be thrown, at cach drop of thc hammer, through the gratnginaperfeet showerbath into 4the open space 'where the machine is located.This mortaiand box are secured loosely to the upright postsby meansofbolts, which pass through saidfeaps and posts, between which t h`eflanges, formed on the sides .ofsaid mortar, play or work.

In iig. 7, 7c is a metal stampshaft, the head of which is abouttwenty-two inches in diameter, tapering, the

first two feet from o`r'above the head, from nine inches in diameter toeight inches in diameter; the whole length above two feet from the head,is eight inc hes diameter. A Thishe'ad is fiattenedon two sides equally,suficient to reduce'it to fourteen' inches in thickness, from side toside. i A

. "k is'the stamp-hammer. Its shape is about the same as that ofthe headto which'it is secured; its depth is about eight inches and a half. Theouter edge of the hammer wears away fasterv than the centre, and forthis'reason I form a depression in the centre, (of its face,) to produceeven wear of the face ofthe hammenhu't I sometimes use them without saiddepressions. This hammeris secured to the stamp-shaft head by a dovetoiljoint, one side of which is straight across from 'side tol side'of thehead; the opposite side is curved, and both sides are cut underdove-tailing. Said dove-tail formed o n the hammer is smaller than theopening .formed in the head for its reception, toadinit a key to enter,and thereby firmly securethe hammer to the head.

Mis' a framework-pulley, madein two parts, and secured together by boltsor screws, and fitted to the stamp-shaft, and having splines whichworkin grooves'formed in the shaft: The office of this pulley is to givea rotary motion to the stamp-'shaftfby meansY of a belt, which runs uponsaid pulley, 7z. The upper end f'this' stamp-shaft is secured' to theouter endet' the steam-cylinder piston-rod z', by means of a Bange-,17,and thc bonnet z' and fastening-bolts z'. j

j is a collar', secured firmly en to the piston-rod by set-nuts. Betweenthis collar `fand the bonnet z' is an elastic washer or spring, twoinches thick. lBetween the-under side of this collarj and the flange iis an elastic packing or spring, four and one-fourth inches thick. Theend ofthe piston-rod is fittedl loosely intoa steel bushing, secured into the upper end of the shaft K. I i A The manner of setting up thismachine and putting it into'operat'ron will be clearly understood from4the foregoing description.

I believeI have thus shown the nature, construction, and advantage ofthis invention, so as to enable others` s killed in the art to make anduse the same therefrom.

Having described myinventionrI will proceed 4to'state what I claim.

1. I. claimfin connection with a quartz-crushing machine, the sills D,when constructedof metal'in place of Wood, asand for the purposedescribed. v

2. I claim arranging the bed-plate J crossurisev of a series ofspring-timbers'E, having their .bearing upon metallic sills D,substantially as and for the purpose described.

3. -I claim the construction of the staves e', tapering in form from thebottoni toward the top, as specified, to suit the bell-form of themortar, substantiallyA as and for the purpose set forth.

4. I claim the'hammer-di'e e, in Acombination with the surroundingstaveholding ring e', substantially as and for the purpose described.

5. I claim the two-part ring. it, secured beneath the top plate, andbetween it and thelining around the stamp-shaft opening, substantiallyas and for-the purpose described.

6. I claim a tubular urn-shape ring-necking, d, made in' two parts, and'secured upon the top plate around the stamp-shaft opening,substantially as and for the purpose describcd. l

7. I claim theconnection of the stamp-shaft K with the `steam-piston t',by means of the bonnet i, flange and collarj, witl'theinterposed'elastic washers, as described, all arrange'dand combinedtogether in the manner and for the purpose set forth.
